There's a pile of your own money sitting in an account right now, and it may not survive the next few months.
If you set aside money in a Flexible Spending Account through your job, that cash usually comes with a use-it-or-lose-it rule.
Miss the cutoff, and the balance doesn't roll into your pocket.
Here's the part that trips people up: the deadline isn't always December 31.
Many plans offer a grace period, typically until March 15, letting you spend last year's funds on new expenses.
Others use a carryover, letting you roll a limited amount forward.
The IRS sets the ceiling on carryover each year, and it changes annually, so your HR department has the real numbers.
Assuming your plan matches your coworker's plan from three years ago is how people lose money.
The tricky detail is that swiping your FSA card at the register isn't what locks in the expense.
What matters is the date the service was provided, not the date you pay the bill.
So a dental visit from last October still counts, even if you're paying the invoice in February.
That gives you a window to hunt down old receipts and submit claims you forgot about.
Start by logging into your FSA portal and checking three things: your current balance, your plan's specific deadline or grace period, and whether you have a carryover.
Then pull together receipts for anything you paid out of pocket last year that qualifies.
Glasses, contacts, prescription copays, therapy sessions, bandages, and even some over-the-counter items can count if you have the documentation.
If you still have money to burn before the cutoff, book the appointments you've been putting off.
An eye exam plus a new pair of glasses can wipe out a few hundred dollars fast.
A dental cleaning, a dermatology visit, or a refill on prescriptions all work too.
Just confirm the service date falls inside your plan's window before you schedule.
One warning worth repeating: don't buy random stuff hoping it qualifies.
Rules tightened a few years back, and items like general vitamins now typically need a prescription to count.
Overspending on things you can't actually claim just creates a paperwork mess.
Also keep in mind that dependent care FSAs run on separate rules from health FSAs.
If you have one of those, the deadlines and eligible expenses are different, so check that account separately.
Parents frequently forget this one exists until it's too late.
Set a calendar reminder for about three weeks before your deadline.
That's enough time to book an appointment, get a receipt, and file a claim without scrambling.
The whole process takes maybe an hour, and it's your money on the line.
The bottom line: this isn't free money from your employer.
It's your own paycheck, set aside on purpose.
Final Thoughts
Treat the deadline like a bill you owe yourself, and you'll stop donating your balance back every year.
